Dr. Joffe just posted a new article on the many negative effects of lockdowns in Canada and in the world as a whole. He really has put in a fantastic effort to source the evidence on the negative effects of the covid-related policies, digging up and critically evaluating nearly 200 international studies. Here is his Table 2 (out of 8).
Highly recommended as a summary document of the masses of evidence now rolling in on the unnecessary self-inflicted disaster that is befalling humanity. The link is https://www.preprints.org/manuscript/202010.0330/v1
